Well, seems that I can learn something here.
what is realy original for the NZ?
Far as I know now;
1. Everbest and MZAG brass taps for KS and SB-models and Civil NZ
2. AW, Everbest and Metrix for WH-NZ and -1
3, The metrix is also to see in the Bedienungsanleitung 1939 DKW NZ250-350
and Bedienungsanleitung DKW NZ350 1941 D605-11
4. Evaga, for DKW NZ 350-1
5. Alno, the last used taps for NZ 350-1
That are in total 7 taps wich could be found on a NZ
I have for the RT 125 the;
ETL-DKW RT125-30-10-42 D605-14
ETL-RT125-30_10_42
and ETL D 605-13_RT125_1944 (Without pictures)
Far as I can see, only the AW 'Frankfurter Model' without Wassersack.
I saw the Metrix-tap on the RT 125nA 1944.
Is there anyone among you who could send a good picture from that 'new' Evega-tap?
Here a picture from a Metrix-tasp in the Bedienungsanleitung DKW NZ350-WH 1941 D605-11
